service worker: off-main-thread script fetch This CL implements OMT service worker script fetch behind a runtime flag. When the flag is enabled, WebEmbeddedWorkerImpl fetches worker script on the worker thread using WorkerThread::ImportClassicScript(). Global scope initialization is delayed until script is fetched to support pausing and resuming worker for update check. See the following doc for detailed explanations and alternative approaches: https://docs.google.com/document/d/1VqVm-kLS0uOCiuSRYhk5iO-qrXc1Zfqj2SAO0fAXEgo/edit?usp=sharing Bug: 924043 Change-Id: I0d2656224c0ec00ff2630f48e21ad6331e03dd38 Reviewed-on: https://chromium-review.googlesource.com/c/1482101 Reviewed-by: Kinuko Yasuda <[email protected]> Reviewed-by: Hiroki Nakagawa <[email protected]> Reviewed-by: Matt Falkenhagen <[email protected]> Commit-Queue: Kenichi Ishibashi <[email protected]> Cr-Commit-Position: refs/heads/master@{#636357}
